The last deepavali big sale from flipkart i bought one 'fossil es4490 jacqueline analog watch - for women' through retailnet. When i open the packet saw an empty box with guarantee card have no details and the box is damaged. Don't buy anything from this buyer last 5ys it's the first time i faced this bad experience from flipkart. What i do for next step against this fraud company to refund the amount back.
